  Pointing A Finger At Network Management Point Products 
By Bruce Boardman
Sometimes it seems management is an afterthought when it comes to network hardware. After all, the management solution from the hardware manufacturer should let the two work together seamlessly, right? We decided to test these point products at our Syracuse University
lab to determine if a vendor's proprietary management application suite helps to manage its networking hardware. It came as no surprise that 3Com Corp.'s Transcend Enterprise Manager is the best solution for managing an all-3Com network. Likewise, O ptivity Enterprise is the best for Bay Networks-based environments, Cisco Works is ideal for Cisco Systems and SPECTRUM Element Manager is best-suited for the management of Cabletron Systems equipment. However, the maturity, consistency and functionality of these products differed greatly.
Breaking It Down Each application suite breaks down network management into roughly four functional areas. The first is the integration of the suite within an overall framework, which includes support for different device types across the same vendor's product lines. Capabilities in this area highlighted the maturity of some of the products. The next functional area is the device or element (hub, switch or probe) configuration and management solution. This area is typically identified by the bitmap image of the device--displayed with blinking LEDs and color-coded twisted-pair jacks. The third functional area is the global tools that manage multiple devices and the connectivity between them, like topology mappings. The last functional area is traffic monitoring. We considered traffic monitoring and its integration into these management point products an important feature. Although virtual LAN (VLAN) and Remote Monitoring (RMON) management are important aspects of network management, we chose not to focus too heavily on these features in this comparison. We did, however, call on both of these management functions, where appropriate, to determine just how well they are integrated into each product. Where n ecessary, Hewlett-Packard Co.'s HP OpenView was used as our network management framework.
3Com Corp. Transcend Enterprise Manager
Transcend requires that you have the right switches paired with th e right applications to make the management functions work. For example, we were able to define VLANs only after we loaded a new version of the software that included the VLAN manager as part of the Unix management application. But, overall, Transcend had by far the fewest inconsistencies that could be attributed to different hardware requiring different management software.

To view the Report card.
Coherent global applications characterize Transcend Enterprise Manager. Status View and Inventory manager, applications within Transcend, provide wide, flexible access to multiple devices. Although not perfect, Transcend is well-integrated and able to access management information across a variety of 3Com switch and hub models.

One of the great ironies of storage technology is the inverse relationship between efficiency and security: Adding performance or reducing storage requirements almost always results in reducing the confidentiality, integrity, or availability of a system.
